James Coleman d11a525008 feat(release): publish an AppImage for each Linux architecture
- Releases now include Midi-Harbor-<version>-<x86_64|aarch64>.AppImage, built from the same binary as the packages and listed in checksums.txt, for distributions without a .deb or .rpm. Opened with no arguments it shows the window, and the daemon it registers runs under the systemd user unit like a package install.
- service install run from an AppImage registers the .AppImage file instead of the executable inside the runtime's temporary mount, which is gone once the process exits. The file is used only when the running executable is inside APPDIR, so a program started from another AppImage, whose APPIMAGE it inherits, still registers itself.
- The AppImage carries only the Avahi client libraries from the Debian 12 sysroot, with their LGPL-2.1 license, found through the binary's RUNPATH rather than LD_LIBRARY_PATH; glibc 2.35 or newer, ALSA, D-Bus and libxkbcommon come from the host, as for the packages.
- Its AppRun starts the binary as midi-harbor, so on X11 the window's class matches the desktop entry instead of the AppImage's file name.
- Building it needs the cross image's new patchelf, file, appimagetool 1.9.1 and type2 runtime 20251108, pinned by checksum, and a sysroot rebuilt to carry Avahi's license; the script stops and names make build-sysroot when that license is missing.

Specifications

One spec per capability, numbered by topic. Each holds its user stories, requirements, success criteria, research and tasks; the architecture, the daemon contract and the command-line contract are in 001, and every spec follows the constitution.

Requirement (FR), success criterion (SC), research (R) and task (T) numbers are unique across every spec, and the code cites them by number. They were given in the order the work was done, so one spec's numbers are not contiguous; the lists below say which spec holds each. The one exception is 014, whose task list started again at T001: its T001 to T034 are cited as 014's.

Spec What it covers
001-service-and-clients The single executable, the daemon, the gRPC contract, the command line, installing the service, packaging; the architecture and the original input
002-configuration The configuration file, applying changes while running, export and import, Apple's setup, capabilities
003-virtual-ports Ports applications on one computer use to talk to each other
004-hardware-devices Attached MIDI hardware and other applications' ports, hot-plug, identity
005-network-ports RTP-MIDI between computers: discovery, invitations, the journal, machines, the automatic port
006-bluetooth-midi Bluetooth LE MIDI, connecting out and advertising
007-routing Routes between any two endpoints, loops, system-exclusive, the repeater
008-resilience Recovery: backoff, sleep and wake, releasing notes, restoring state, the MIDI service dying
009-observability State, counters, history, the monitor, the diagnostic report
010-graphical-interface The libcosmic window and its redesign
011-midi-service-crash-warning Warning that other apps may have lost MIDI; when traffic last moved each way
012-test-note Sending a note out of an endpoint to test what listens
013-windows-support Windows as a first-class platform
014-mac-app-store-mode The sandboxed App Store build, run from the menu bar
015-mac-menus The menus on macOS: File, Edit, View, Window and Help
016-app-store-submission Building the package App Store Connect takes
017-appimage The AppImage for Linux, and registering the daemon from it
